Reaction Steps
A mixture of 6-iodo-2-methylbenzo[d]thiazole (275 mg, 1 mmol), but-3-enoic acid methyl ester (100 mg, 1.2 mmol), diacetoxypalladium (22 mg, 0.1 mmol) and triethylamine (304 mg, 3 mmol) MeCN (8 mL) is heated in a microwave apparatus at 130° C. for 30 minutes. The solvent is removed under reduce pressure and the residue is purified by flash chromatography (heptane:EtOAc, 2:1) to give (E)-4-(2-methyl-benzothiazol-6-yl)-but-3-enoic acid methyl ester. MS 248.3 (M+1).
